Anatomy of orbit. Orbit anatomy in anatomy the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. The contents of the orbit are separated and supported by multiple. Borders of orbit roof floor base apex medial and lateral walls of orbit superior orbital fissure inferior orbital fissure superior orbital foramen inferior orbital foramen optic.

The shape of the orbit resembles a four sided pyramid to begin with but as one goes posterior it becomes three sided towards the apex. Orbit can refer to the bony socket or it can also be used to imply the contents. Anatomy of the orbit the skull is composed of two segments the cranium and the face.

The volume of the orbital cavity in an adult is roughly about 30cc. The cranium is the major portion and it consists of three unpaired bones the sphenoid occipital and ethmoid bones and three paired bones the frontal parietal and temporal bones. Development orbit develops around the eyeball orbital walls derived from cranial neural crest cells which expand to form frontonasal process maxillary process lateral nasal process maxillary process medial inferior and lateral orbital walls capsule of forebrain forms orbital roof.

It also protects this vital structure. The orbit which protects supports and maximizes the function of the eye. It emphasizes the aspects of eye and orbit anatomy that are most relevant to clinicians in training providing the practical real world foundation necessary for practice.

The clinical essentials achieves the impressive task of presenting ophthalmology residents optometry residents and optometry students with the clinical essentials of ocular anatomy as a foundation for patient care. Orbit supports the eye and ensures that this organ functions in an optimal manner. When orbital cellulitis occurs its most likely source is direct extension from the ethmoid sinuses because the thin bone of the medial wall is easily penetrated by expanding masses from the sinus.

In the adult human the volume of the orbit is 30 millilitres 106 imp fl oz. Anatomy of the eye and orbit.
